Description

[Detailed Description of the Invention] The present invention relates to a terminal fixing device for a battery case.

Conventionally, a battery terminal of a battery case has been fixed by forming a cut-and-raised piece on the side of the terminal, and press-fitting the cut-and-raised piece into an insertion groove formed on the inner surface of the battery case.

However, in this case, when the battery is removed, a force in the direction of falling off is also applied to the battery terminal, so that the battery terminal has the disadvantage that it is easily shaken or fallen off by mere press-fitting. Moreover, since the lead wires connected to the battery terminals are exposed inside the battery case, the insulation distance between the battery and the battery is short, and the lead wires get in the way, making it difficult to store the battery.

The present invention was created in view of these drawbacks.
The object is to provide a terminal fixing device for a battery case that can always stably fix a terminal, ensure an insulating distance between the battery and a lead wire, and allow easy storage of the battery.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

Fig. 1 shows an example in which the present invention is applied to an air pot with a liquid level display device, in which 1 is a metal exterior body constituting the pot body, 2 is a medium bottle housed inside the exterior body, and 3 is the exterior body 1. Shoulder body placed and fixed on the upper end,

The other end of the electrode 11 is connected to a liquid level display device via an electrode lead wire 13.

A spout cover 15 is attached to the front of the exterior body 1, and inside the spout cover there is a water conduit cover 16 that holds a printed circuit board 17 on which a liquid level display circuit is mounted, and a liquid inlet. A water guide pipe 22 extending downward from the liquid injection pipe 7 of the inner stopper 6 is housed and fixed. A display element 18 is attached to the printed circuit board 17, and this display element displays the amount of liquid in accordance with changes in the liquid level within the medium bottle 2. Note that 19 is a display cover.

23 is a battery case integrally molded into the shoulder body 3;
Inside this are two batteries 4 that are the power source for the liquid level display device.
8 and 49 are housed therein, and a battery cover 50 covers the opening of the battery case 23. battery case 2
3 has a recess 24 that is open on the outer circumferential side as shown in FIGS. 2 to 4, and has a horizontally protruding eaves 25 on the upper end, and guides for attaching the battery cover on both sides. A groove 26 is formed. The battery case 23 has a screw insertion hole 27 provided at the bottom of the recess 24.
By screwing screws 28 (see FIG. 1) into the exterior body 1 through the screws, the housing 1 is tightly fixed to the exterior body 1.
First to third insertion grooves 29, 30, 31 are formed on the opposing upper and lower inner surfaces of the recess 24 of the battery case 23, and a shallow bottom is formed at the bottom of the recess 24 corresponding to the intermediate part of these insertion grooves. First to third recesses 32, 33, 34
is formed. Further, a through hole 35 communicating with the inside of the exterior body 1 and a lead wire insertion recess 36 connecting the second and third recesses 33 and 34 and the through hole 35 are formed on the bottom surface of the recess 24. Four fitting claws 37 are provided protruding from the left and right inner surfaces of the recess 24.

38, 39, 40 are battery terminals, and as shown in FIG. 5, the first terminal 38 has two contact parts 38a, 38.
b, a locking piece 38c having cut-and-raised claws on both sides, and an L-shaped bent piece 38d in the center;
The terminals 39 and 40 are contact portions 39a and 40a, respectively.
It has locking pieces 39b, 40b having cut and raised claws, and L-shaped bent pieces 39c, 40c. In addition,
Bent parts 39c, 40 of second and third terminals 39, 40
Power supply lead wires 41 and 42 are connected to c, and these lead wires 41 and 42 are connected to a liquid level display device.

Reference numeral 43 denotes a synthetic resin battery panel placed at the bottom of the recess 24 of the battery case 23. A partition wall 44 for partitioning the batteries is provided in the center on the surface thereof, and a partition wall 44 for partitioning the batteries is provided on both sides. A display section 45 is engraved to display the following. The upper edge of the battery panel 43 has a protrusion 46 that fits between the first insertion grooves 29, and the lower edge has a protrusion 47 that fits between the third insertion grooves 31. 43 is prevented from being installed upside down.

Here, a method for fixing the battery terminals 38, 40 to the battery case 23 will be explained. First, terminal 38~
By press-fitting the 40 locking pieces 38c, 39b, and 40b into the insertion grooves 29 to 31 of the recess 24, the terminal is temporarily fixed in the vertical and horizontal directions, and the bent piece 3
8d, 39c, 40c are the first to third recesses 32 to 3
Fits into 4. The power feeding lead wires 41 and 42 led out from the through hole 35 and connected to the second and third terminals 39 and 40 are inserted into the lead wire insertion recess 36. Next, when the battery panel 43 is fitted into the recess 24, both side edges of the battery panel 43 are forcibly fitted into the fitting claws 37 and attached to the bottom of the recess 24, and the upper and lower edges of the battery panel 43 are Press the surfaces of the bent pieces 38d, 39c, and 40c of the terminals 38-40. As a result, the terminals 38 to 40 are placed vertically relative to the recess 24. Before and after. Positioned and fixed in the left and right direction. After fixing the terminals as above,
When the two batteries 48 and 49 are stored according to the display section 45 of the battery panel 43, the + and - poles of each battery are connected to the contact portions 38a, 39a and 3 of the terminals.
8b and 40a and become electrically conductive.

In the above embodiment, the case where two batteries 48 and 49 are connected in series and housed is shown, but the present invention can be similarly applied to the case where one or three or more batteries are housed. Further, the battery panel 43 is not limited to a flat panel, but may be formed in a corrugated shape with an arcuate cross section so as to match the outer peripheral surface of the battery. Furthermore, the attachment of the battery panel 43 to the battery case 23 is not limited to forced fitting with the fitting claws 37, but may also be done by screwing. In this case, the screws 28 for attaching the battery case 23 to the exterior body 1 may also be used. You can.

As is clear from the above explanation, according to the present invention, a bent piece is formed on the terminal, and the bent piece is pressed by the peripheral edge of the battery panel attached to the bottom of the recess of the battery case. Since the terminals are fixed in place, the terminals will not wobble or fall off even if the battery is repeatedly attached and detached, so it can always be fixed stably. In addition, since the battery panel covers the outer surface of the lead wires connected to the terminals, it is possible to secure an insulating distance between the battery and the lead wires, and the lead wires do not get in the way, making it easier to store the battery. be.
